I just love the stuff from Makezine — tinkering and programming bring back such good memories. If you like tinkering with little electronic devices and programming patterns, it’s definitely worth ...

This is a simple LED Cube circuit designed using 555 timer. It can be very useful for home decoration purpose and home lighting systems. Many LED Cube circuits are available in the markets which are ...

[portreathbeach] built this simple 3x3x3 LED matrix. It uses a PIC16F690 in a ZIF socket for the brains. Each layer has nine LEDs with the cathodes tied together. The anodes from each LED are ...

thus creating a 3x3x3 cube. The LEDs are controlled using a trinket micro controller (http://www.adafruit.com/products/1500) and two shift registers (http://www ...

LED cubes are cool, but they’re usually pretty big and clunky. [One49th] set out to make one of the smallest LED cubes we’ve seen yet, and he’s shared how he did it in his Instructable! His first LED ...
